我有一个问题,在我的Mac上用山狮和java 7开始玩2.2.0应用程序:

[ERROR] Terminal initialization failed; falling back to unsupported

我有一个整数列表(当前),我想检查此列表是否包含预期列表中的所有元素,甚至列表中的一个元素notExpected,因此代码如下所示:

    List<Integer> expected= new ArrayList<Integer>();
    expected.add(1);
    expected.add(2);

    List<Integer> notExpected = new ArrayList<Integer>();
    notExpected.add(3);
    notExpected.add(4);

    List<Integer> current = new ArrayList<Integer>();
    current.add(1);
    current.add(2);


    assertThat(current, not(hasItems(notExpected.toArray(new Integer[expected.size()]))));

    assertThat(current, (hasItems(expected.toArray(new Integer[expected.size()]))));

好久不过.但是当我补充说

    current.add(3);

测试也是绿色的.我滥用了hamcrest匹配器吗？顺便说一句.

    for (Integer i : notExpected)
        assertThat(current, not(hasItem(i)));

给了我正确的答案,但我认为我可以很容易地使用hamcrest匹配器.我正在使用junit 4.11和hamcrest 1.3
